VThis invention relates to windshield operating mechanism and it has for its objects to provide a simple and relatively inexpensive device of this character that may be easily and 1i quickly instal'ledfin either new or usedicars and conveniently operated with one hand to instantly swing the Windshield sash to `,any

desired position within a wide range of adjustment and lock it securely insuch position. The device serves also to hold the sash tightlyv closed. A further object is to provide an extensible operating handle for the mech'- anism whereby the leverage maybe increased and the operation thus rendered easier and which enables the handle tobe contracted or folded back out of the way when notin use.

Embodiments of the invention through which' the foregoingobjects are attained are illustrated in 'the accompanying drawings 5520 wherein Fig. 1 is a side elevation of the device `,applied to a windshield, `parts ofthe frame and cash of the windshield being shown in section; Fig. 2 is an elevational4 view taken asthough looking from the left to Fig, 1;

v P Fig; '3 lisa sectional detail on the line 3"-3 of Figfl; Fig. 4 is a :sectionalside elevationl rof a modified form of the invent-ion; and "Suis a plan view of a further modification. l y rlv` rDescribing the parts by reference charac- -ters, 1 represents the top member of the windshield frame to the loweredge of-Which is connected, by theusual so-called cpiano hinge 2, a windshield sash 3;

` Fastened as by screws 5 tothe inner side vof the frameVv member 1 is a bracket 6 to which a Ascrew -10 thatis'shown as providedV with.

an'elongated cylindrical head ll'that has a longitudinal"I groove 12 along lone 4sideV that stops Ashort ,of the outer endfo'f the head. Telescoping, over thehead of the screw isa sleeve lthatgincorporates an operating hanthe handle.` The innerend of the screw is to bindagainst the curved edge of the bracket dle'14,;shownas spherical in form. Aninf, Ivwa'rdly projecting pin is carried by the sleevelland normally this pin is in advance of the open end ofthe slot 12 so that'thc handle may be` turned to dispose'the pin out of register with the slot 7 ,but whenV it is desired to extend the handlethe latter is rotated until thepin is in alignment With the slot k12 when it is free ,tov enter the slot and thus-.permit .the sleeve 13 to slide Voutwardly along the head 11 until such movementis arrested by the engagement of'said pin with the closed end'of the slot. When the pin is in the slot it constitutes a drivingconnection between the operating handle and the screw so that the screw maybe turned by means of l i arrangedito engage thev'curved edge ofthe bracket 6 and by turning the screw' inwardly against they bracket theA leverA 8 may be locked -in any position to which it is adjusted.

Secured by suitable fastening means, such as bolts 16, to the top of thesash 3, is a fitting 17. 1 `This fitting has laterally spacedears 18 between 'which the lower end of ajlink 19 `isdisposed,land a pin or rivet-A20 is engaged through registering apertures of the earsy 18 '7' and link'19, thereby to pivotally connect the parts together. The oppositeend of the'link is pivoted at 2l to the lever '8. When it is desiredto adjust the windshield sash, the operator grasps the handle Mend SQ rotatesjit until he feels the pin l'enter the A slot' 12 of the'screwV head 11. lHethen slides the handle` outwardly along said head,`there by to increase'the'effective length of the lever 8, and rotates the operating handleto retract the screw Vl0 so i as to withdraw' the screw from binding engagement withA the bracket 6.

-Vith the parts in this condition, the operator may swing the handleso as to adjust thefwind shield sash to l`yany desired position through t the intervention ofthe. link 19. When the desired' adjustment of the sash has been attained'he turns r`theo'perating handle in a direction to advance thescrew and cause it andl 'thus' lock` the parts',V inthe'ir Ynewlyacquired position. The handle maynovv be shoved inwardly along the.: screw Yuntil the.

pin 15 jleavesf'the slot l2'and byturning the handle' so as lte move .the pin kout of line with the slot the handle is prevented from sliding outwardly on the head of the screw. Obviously by raising the lever 8 to its extreme upper position and locking it by means of the screw 10, the sash may be secured in closed position.

In the form of the invention illustrated in Fig. 4, the curved edge of the bracket 6 is formed Vwith teeth wherewith the toothed edge of a member 25 cooperates, saidniember being in the natu-re of a plunger that is guided within an elongated boss 2610i the lever 8. Said boss is counterbored to accommodate Y a spring 27 which serves to advance the member toward the bracket. In the present case, the screw 10 is adapted to be extended forwardly by the operating handle 14- so as to positively prevent retraction of the member 25 against ordinary forces tending to swing the Y windshield sash to closed position; and the parts may be positively locked by advancing the screw 10 so as to prevent retraction of the member 25.

In the modilication of Fig; 5, the bracket 6 may be the same' as that shown in Figs. 1 to 3, and the outer end of the lever 8 is bifurcated and extends laterally in opposed relation to the curved edge of the bracket. lithin the bifurcated end of the lever 8 is pivoted, on a pin 30,- the inner end of an operating handle 81, said inner end being in the nature of a cam, which, when' the operating handle is swung tothe dotted line-positionin Fig. 5, binds against the edge of thev bracket.

In this case when it is desired to adjust the windshield sash the operating handle 3l is swung into approximate alignment with Vthe lever 8 and through it the lever is adjusted so asY to effect the desired adjustment of the sash and when this condition is reachedthe handle is swung to the sideso as to cause its cam to engage the edge of the bracket and lock the parts against movement.
